Secrets of the Catoctin Mountains: A Quiet Corridor That Built America's Spycraft
A three-hour guided exploration of the Catoctin and South Mountain region’s hidden role in World War II and the Cold War—this guide explains what you’ll see and why those quiet ridgelines mattered.
Secrets of the Catoctin Mountains: A Quiet Corridor That Built America's Spycraft.
The Mountain Spies Tour follows a narrow mountain corridor just miles from Washington, D.C., where peaceful forests and resort towns masked a concentrated effort to build American intelligence capability. Over the course of the outing guests trace how wartime improvisation in the Catoctin and South Mountain region—training, interrogation, covert operations and continuity planning—was folded into a permanent national-security architecture.
